Syntax

public abstract class Feature2D : UnmanagedObject, 
	IAlgorithm

Public MustInherit Class Feature2D
	Inherits UnmanagedObject
	Implements IAlgorithm

public ref class Feature2D abstract : public UnmanagedObject, 
	IAlgorithm

[<AbstractClassAttribute>]
type Feature2D =  
    class

        interface IAlgorithm
    end

The Feature2D type exposes the following members.

Constructors

	Name	Description
	Feature2D	Initializes a new instance of the Feature2D class

Methods

	Name	Description
	Compute	Compute the descriptors on the image from the given keypoint locations.
	Detect	Detect the keypoints from the image
	DetectAndCompute	Detect keypoints in an image and compute the descriptors on the image from the keypoint locations.
	DetectRaw	Detect the features in the image
	Dispose	The dispose function that implements IDisposable interface (Inherited from DisposableObject.)
	DisposeObject	Reset the pointers (Overrides DisposableObjectDisposeObject.)
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Destructor (Inherited from DisposableObject.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ReleaseManagedResources	Release the managed resources. This function will be called during the disposal of the current object. override ride this function if you need to call the Dispose() function on any managed IDisposable object created by the current object (Inherited from DisposableObject.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Extension Methods

	Name	Description
	Read	Reads algorithm parameters from a file storage. (Defined by AlgorithmExtensions.)
	Write	Stores algorithm parameters in a file storage (Defined by AlgorithmExtensions.)

Fields

	Name	Description
	_algorithm	The pointer to the Algorithm object.
	_feature2D	The pointer to the Feature2D object
	_ptr	A pointer to the unmanaged object (Inherited from UnmanagedObject.)

Properties

	Name	Description
	DescriptorSize	Get the number of elements in the descriptor.
	Feature2DPtr	Get the pointer to the Feature2D object
	Ptr	Pointer to the unmanaged object (Inherited from UnmanagedObject.)
